PRINTING DEVICE. y Application iisd December 1, i926. serial No. 151,878. x

This invention is concerned'with means for .18 indicates feed rollers and 19 is an ejectleveling a portionof a printing form to cause ing device forv the paper. Theplaten, feed it to stand in surfaceregistration with anrollers and'ejecting'device are all geared with other portion, as for instance leveling address the drum, by gearingnot shown. f 4 5 plates so they may stand thes'ame height-to-k A portion" of the segment, adjacent lone 60 paper witha body form on the same vprinting edge, is internally thickened as shownA at 20 f member. Figs. 1, 3 and 6, and in this thickened portion VMy invention is particularly designed for is a rectangular 'recess'v21- In this'recess is a employment of an addressingy multigraph. saddle block 30 onv which the address plate A y Such machine comprises a rotary drum may seat. The under surfacefof this saddle 65 adapted to carry thebody form and a changeblock is slightly rinclined Ias shown in Fig. 1 i able address form, and a rotary platen with .and such vsurface vbears against a complemenwhich both forms coact'.v` lBoth' the body form tary inclined Aupper surfaceV on a shim block and address plate may be compound members 35 also occupying thel` recess.l A stud 40 consist-ing of a holding plate with raised promounted in the saddle blockV extends radially 70 jectionsfand embossed printing strips mountinwardthrough a slot 41 on the shimvblock ed on the projections. I have found that while and loosely through a hole 42 in the segment, it is comparatively simple to gage address and within the segment is surrounded by a plates so that they all stand the same height, compression spring 44, adjusted by av nut45 it is much more difficult to gage a blanket of on the stud. The spring 44 maintains the sad'- 75 page size.

acts with-the printing Vservice on the drum. 128,7 6() filed August 12,1926,by II. C. Osborn `110 and assigned to my assignee, The American Multigraph Company. In such case, it comprises a trough shaped sheet metal member having parallel corrugations a from the top of which eXtend lateral lips a which stand some distance above the body of the plate and thus adapted to carry embossed printing strips B resting thereon and having inward.

flanged edges which overhang the projections. The edges of the address plate are preferably curled back on themselves asv lspring 76. vWhen the address plate is in printing position, its lett end has cleared a finger latch 77 which is pressed radially outward by a spring 79l (Fig. 4)` occupying aI boss 78 on the latch. At the end of the printing impression finger pressure on the outer face of the boss, forces the latch inward to releasethe address plate, and the spring 7 6 discharges the plate intoposition where it may be readily grasped by the operator.

The'blanket which' cooperates `with the address plate is designated C. It comprises-a sheet metal member having upstanding' corrugations c with lateral lips 0 on which are mounted embossed printing stripsl). One end of this blanket, as shown, is hookedrover the overhanging portion of the longitudinal rib 70,'while the other end isanchoredto a movable bar 80 carried byspringarms 8l embracing the shaft 12. Screws 83 force the bar 80 away from the segment to tightenthe blanket.

, a sheet metal bridge extending across the,

The drawings show ati90 in Figs. 2 and 7,

address plate channel. Mounted in the printing drum are spools 92 from whichv extends an inkingribbon 93 which 'overlies the blanket, bridge and address plate channel and the addressplate when in place. It-v is to be nnderstood that inoperation the printing drum is given periodic rotations, and during the pause between consecutive rotations the address plate is discharged and aii'resh'plate in- Y sert-ed beneath the bridge 90which supports the ribbon atthat region.
